Chris is checking to determine if the expressions 2 (x + 3) and 2 x + 4 + 2 x are equivalent. When x = 1, he correctly finds that both expressions have a value of 8. When x = 2, he correctly evaluates the first expression to find that 2 (x + 3) = 10.

What is the value of the second expression when x = 2, and are the two expressions equivalent?
The value of the second expression is 8, so the expressions are equivalent.
The value of the second expression is 10, so the expressions are equivalent.
The value of the second expression is 12, so the expressions are not equivalent.
The value of the second expression is 16, so the expressions are not equivalent.

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

what level of math? also i don't need to be paid if i can you.

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
